OBSTETRIGAL INSTRUMENT.

Application filed May 4,

To all whom it may concern:

Be it known that I, ATVILL Brno, a c1t1zen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Obstetrical Instruments, of which the following is a specification.

My invention relates to obstetrical instruments of the character employed in removing pigs or other animals from themother, and my object is to provide a set of instruments whereby an unborn animal can be readily located, seized and removed from the mother without injury to either.

In order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. 1 is an elevation of the device in pos1- tion preparatory to forming a loop in a cable constituting a part of said devlce.

rig. 2 is an elevation of the device showing the loop formed in the cable.

rig. 3 is a detail perspective view of a supplemental member.

Fig. 4: is a perspective view of a main member.

In carrying out the invention, I employ a main member 2 consisting, preferably, of a flexible rod provided at its rear end with a handle 4 and at its forward end with an eye 6 and a hook 8.

10 designates the supplemental member which also consists, preferably, of a flexble rod provided at its rear end with a spiral coil 12 and at its forward end with an eye 14. The coil 12 constitutes a handle and it may also be introduced into the mother for a purpose which will hereinafter appear.

16 designates a cord or cable which extends freely through the eyes 6 and 1 1 of the main and supplemental members 2 and 10, respectively, and has its ends tied in knots 18 to prevent it from being withdrawn from said eyes 6 and 14.

In removing pigs from a sow, the main member 2 is introduced into the sow with the eye 6 foremost until the pig to be withdrawn is located. The supplemental member 10 is then introduced and slid forward on the cord 16 until the eye 14 contacts the eye 6. The

supplemental member 10 is then manipulated to form the cable 16 into a loop 20 around the pig and engage one side of said loop 20 in the hook 8 after which the outer end of Specification of Letters Patent.

the cable 16 is drawn taut to cause the loop 20 to firmly grip the pig which is then with- 1 drawn by pulling outwardly upon the members 2 and 10 and the cables 16.

Sometimes the pig becomes lodged and must be pushed forward into the sow before being extracted. In such cases the supplemental member is reversed and the pig is tion and arrangement of parts as properly fall within the spirit and scope of the claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. In a set of instruments of the character described,'a flexible rod having an eye and a handle, an element projecting from said main rod adjacent the eye, a cable connected to said eye, and a supplemental flexible rod connected to said cable and adapted to form the same into a running loop by drawing it through the element projecting from the main rod.

2. In a set of instruments of the character described, a main member having an eye, and a hook, a cable connected to said eye, and a supplemental member slidably connected to said cable and wherebv a running loop may be formed in said cable, by drawing it through the hook.

3. In a set of instruments of the character described, a main member, a projection on said main member, cable connected to said main member, a supplemental member coiled at one end and provided at its opposite end with an eye through which the cable freely extends, said supplemental member being adapted to form the cable into a running loop, by drawing it through the projection on the main member.

In testimony whereof I affix my signature, in the presence of two witnesses.
